CROSS-REFERENCE TO RELATED APPLICATIONS

This application is the National Stage filing under 35 U.S.C. 371 of International Application No. PCT/KR2022/000206, filed on Jan. 6, 2022, which claims the benefit of earlier filing date and right of priority to Korean Application No. 10-2021-0004116, filed on Jan. 12, 2021, the contents of which are all hereby incorporated by reference herein in their entirety.

TECHNICAL FIELD

The present disclosure relates to a display device linked to a vehicle and an operating method thereof, and more particularly, to a display device linked to a vehicle and configured to communicate with a system to display augmented reality (AR) digital signage on a floor-by-floor basis in a building in a driving image of a vehicle floor and an operating method thereof.

BACKGROUND ART

For safety and convenience of a user who uses a vehicle, various sensors and devices are disposed at the vehicle, and functions of the vehicle are diversified. The functions of the vehicle may be divided into a convenience function for promoting driver's convenience, and a safety function for enhancing safety of the driver and/or pedestrians.

The convenience function of the vehicle has a development motive associated with the driver's convenience, such as providing infotainment (information+entertainment) to the vehicle, supporting a partially autonomous driving function, or helping the driver ensuring a field of vision at night or at a blind spot. For example, the convenience functions may include various functions, such as an active cruise control (ACC), a smart parking assist system (SPAS), a night vision (NV), a head up display (HUD), an around view monitor (AVM), an adaptive headlight system (AHS), and the like.

The safety function of the vehicle is a technique of ensuring safeties of the driver and/or pedestrians, and may include various functions, such as a lane departure warning system (LDWS), a lane keeping assist system (LKAS), an autonomous emergency braking (AEB), and the like.

Recently, a technology for augmented reality (AR) that outputs a graphic object through a vehicle's windshield or head-up display (HUD) or that outputs a graphic object to an image captured by a camera to additionally output the graphic object to the real world is being actively developed. In particular, by utilizing such AR technology, the development of technologies for guiding a route to a driver through AR technology or for exposing various additional information or advertisements related to points of interest (POI) existing on a route is expanding.

Meanwhile, various guidance or advertisements through AR technology are expressed in the form of AR objects over an actual driving image. Thus, there was a sense of separation from reality, and there were limitations in providing a variety of information at once.

Also, there is a limitation in that when various announcements or advertisements through augmented reality (AR) technology are displayed on a driving image as described above, a building's shape based on a driver's viewing angle, a vehicle driving situation, a driver's individual tendency, and nearby traffic and structural environments cannot be flexibly reflected.

Furthermore, there is another limitation in that once an announcement or advertisement using AR technology is displayed at a predetermined position (e.g., overlapping with or adjacent to an associated object), the display position cannot be varied according to the environment changing due to vehicle driving. Accordingly, there is a problem in that the visibility of an announcement or advertisement using AR technology is reduced.

Advantageous Effects of Invention

The advantages effects of the digital signage platform providing apparatus, the operating method thereof, and the system including the same according to the present disclosure are as follows.

According to some embodiments of the present disclosure, by mapping augmented reality (AR) signage to a building in a driving image and displaying the AR signage to be closely similar to a real signboard, it is possible to solve the awkwardness caused by artificially displaying an AR object on a driving route screen in a conventional manner.

According to some embodiments of the present disclosure, it is possible to solve the conventional limitation of displaying only one advertisement in one area even if augmented reality (AR) technology is used, and thus advantageously, it is possible to provide extensibility for providing a plurality of various advertisements to one building.

According to some embodiments of the present disclosure, even after the AR digital signage is mapped to the display area of the building on a floor-by-floor basis, it is possible to flexibly reflect the shape of a building based on a driver's view, a driving situation of a vehicle, preference, and nearby traffic and structural environments to vary the location of the display area. Accordingly, it is possible to enhance the visibility of the displayed AR digital signage.

According to some embodiments of the present disclosure, when conditions for a vehicle to enter a building area are satisfied, it is possible to significantly improve visibility by displaying AR digital signage on an AR carpet on a road differently from the conventional method of mapping and displaying AR digital signage on a building on a floor-by-floor basis.

According to some embodiments of the present disclosure, by mapping and displaying a plurality of pieces of AR digital signage and an AR carpet on a road in a driving image rather than on a building in order to secure the visibility of advertisement signage while a vehicle is about to or is expected to enter the building, it is possible to help safe driving because visual information is provided on a road ahead without the need for a driver to change his or her gaze to the building.

According to some embodiments of the present disclosure, when the appearance of an obstacle is detected in the driving direction of the vehicle, it is possible to enable a driver to reliably recognize the obstacle and drive safely by stopping the display of the AR carpet and moving and mapping the image of the floorwise AR digital signage to another display area in the driving video or increasing the transparency of the AR digital signage and mapping the AR digital signage.

Alternatively, in other embodiments, the AR engine 827 may be implemented by the user terminal 200, the user interface device 200 (see FIG. 7 ) of the vehicle shown in FIG. 7 , or a processor included in the navigation system 770 or may be implemented by a separate terminal, apparatus, or cloud server.

In response to the AR rendering request, the AR engine 827 may perform AR rendering (831) on a route of navigation (832) (or 2D or 3D map information on the basis of the AR-merged (825) information or data in real time. Thus, the actual driving road and the viewpoint of the screen in which the AR digital signage is to be rendered are matched with each other.

The result of rendering through the AR engine 827 may be transmitted to the user terminal 200. Based on the rendering result, the user terminal 200 may map the AR digital signage to corresponding floors of the building in the driving image displayed on the display of the user terminal 200 or a display device of the vehicle 100, for example, a center information display (CID), a cluster, a head-up display (HUD), a room mirror display, a rear-seat entertainment (RSE) system, a vehicle windshield/dashboard, or the like and output the mapped AR digital signage on a floor-by-floor basis.

In this case, a driving image captured or reflected through a camera sensor provided in the vehicle 100 is output to the display of the user terminal 200 or a display or LCD screen provided in the CID, HUD, or RSE of the vehicle 100, and AR digital signage is mapped to the corresponding driving image. On the other hand, a vehicle display device such as an AR navigation system maps AR digital signage to the vehicle windshield or dashboard by direct projection through a laser sensor or the like provided in the vehicle 100.

Therefore, in the present disclosure, a “driving image” includes an image captured through a camera sensor (or smart glasses including such a function, an image reflected on the LCD screen through a camera sensor, an actual space image displayed on a windshield or dashboard into which AR digital signage is directed projected, digitally-twinned 3D image, and the like.

Meanwhile, the user terminal 200 may transmit the mapping result to the digital signage platform providing apparatus 800 such that the display area in which the image of the AR digital signage is mapped and the display area of the building in the driving image or the actual driving road are matched with each other and may receive an image correction request from the digital signage platform providing apparatus 800 continuously and in real time.

The plurality of user terminals 200_1, 200_2, and 200_3 may communicate with the information processing system 800 over the network 50. The network 50 may be configured to enable communication between the information processing system 800 and the plurality of user terminals 200_1, 200_2, and 200_3. For example, depending on the installation environments, the network 50 may be configured as a wired network such as Ethernet, wired home network (power line communication), a telephone line communication device, and RS-serial communication, a wireless network such as a mobile communication network, wireless LAN (WLAN), Wi-Fi, Bluetooth, and Zigbee, or a combination thereof. The communication scheme is not limited to the above networks and may include short-range wireless communication between the user terminals 200_1, 200_2, and 200_3 as well as a communication scheme that utilizes a communication network (e.g., a mobile communication network, the wired Internet, the wireless Internet, a broadcast network, a satellite network, etc.).

Alternatively, for example, the user terminal may be a vehicle display device such as a CID, a cluster, a HUD, a room mirror display, an RSE, etc.

Also, the three user terminals 200_1, 200_2, and 200_3 are illustrated in FIG. 9 as communicating with the information processing system 800 through the network 50, but the present disclosure is not limited thereto. A different number of user terminals may be configured to communicate with the information processing system 800 via the network 50.

For example, the information processing system 800 may receive a request for route guidance or a request for the provision of AR digital signage from the plurality of user terminals 200_1, 200_2, and 200_3. The information processing system 800 may collect and merge information for generating AR digital signage in response to the received request, render the information in a display area to be displayed with AR signage, and provide the rendered information to the plurality of user terminals 200_1, 200_2, and 200_3.

Specifically, the information processing system 800 may receive sensing data of the vehicle 100 (see FIG. 8 ), request the cloud server to provide map information associated with the received vehicle sensing data, and receive and store the map information. The information processing system 800 may detect a building area including a plurality of pieces of POI information, calculate spatial coordinates of the detected building area, and acquire floor number information for each of the plurality of pieces of POI information on the basis of the received map information.

Also, the information processing system 800 may calculate the reference point of the building area for displaying content information related to the plurality of pieces of POI information on the basis of the sensing data of the vehicle and the spatial coordinate and floor number information of the building area. Also, the information processing system 800 may perform a rendering request to display AR digital signage corresponding to the content information related to the plurality of pieces of POI information in the display area determined based on the calculated reference point. Here, the rendering request may be performed by an AR engine, and the AR engine can be understood as referring to the operation of processors of the user terminals 200_1, 200_2, 200_3, a processor of an electric device embedded in the vehicle, a processor of the information processing system 800, or a processor of a linked apparatus, server, or system.

Subsequently, the information processing system 800 may transmit the result of the AR rendering request to the user terminals 200_1, 200_2, and 200_3 and may transmit an image correction request such that the user terminals 200_1, 200_2, and 200_3 map an image of the AR digital signage corresponding to the result of the rendering request to a display area of a building in a driving image acquired through a vision sensor on a floor-by-floor basis. The user terminals 200_1, 200_2, and 200_3 may map and output the image of the AR digital signage to the display area of the building in the driving image on a floor-by-floor basis and/or may map and output the image of the AR digital signage on a floor-by-floor basis in response to the image correction request received from the information processing system 800.

FIG. 10 is a diagram illustrating a configuration of the digital signage platform providing apparatus 800 according to an embodiment of the present disclosure.

In some embodiments, the digital signage platform providing apparatus 800 may be implemented as a device embedded in the navigation system 770 or the user terminal 200 embedded in or linked with the vehicle 100, as described above. Also, in some embodiments, the digital signage platform providing apparatus 800 may be implemented as a platform provided by the cloud server. Also, in other embodiments, the digital signage platform providing apparatus 800 may be implemented in the form of a separate terminal, device, system, or program independent of the vehicle 100 and the cloud server.

Referring to FIG. 10 , the digital signage platform providing apparatus 800 according to an embodiment of the present disclosure may include a communication module 810, a data collection and processing module 820, an AR rendering request module 827, and a memory 840. However, the present disclosure is not limited thereto, and the digital signage platform providing apparatus 800 may include fewer elements or more elements. For example, the digital signage platform providing apparatus 800 may include an additional element such as an AR engine formed to perform rendering.

The communication module 810 is formed so that the digital signage platform providing apparatus 800 can communicate with the cloud server 900 (see FIG. 8 ), the vehicle 100, and the user terminal 200. For example, in order to perform communication, the digital signage platform providing apparatus 800 may include at least one of a transmitting antenna, a receiving antenna, or a radio frequency (RF) circuit or an RF device capable of implementing various communication protocols or may include a wired or wireless interface device.

The data collection and processing module 820 collects, filters, and processes information that is related to vehicle sensing data, image data, a user input request, map information, and content information such as the location, the number of floors, and advertisements of the building area including the plurality of pieces of POI information and that is received through the communication module 810. Also, the information collection and processing module 820 may perform a series of operations for filtering, processing, and merging one or more pieces of information to generate AR digital signage corresponding to the content information related to the plurality of pieces of POI information.

The AR rendering request module 827 performs a rendering request to generate AR digital signage corresponding to the plurality of pieces of POI information. The AR rendering request module 827 causes the AR engine to, in operative association with a route guidance map of the vehicle, match the viewpoint (first viewpoint) of the driving image or the actual driving road to the viewpoint (second viewpoint) of the screen in which the AR digital signage is to be rendered, determine the display area in which the AR digital signage is to be rendered, and vary the display area continuously or in real time.

The memory 840 includes programs and instructions related to the overall operation of the digital signage platform providing apparatus 800. The memory 840 is communicatively connected to at least one processor (not shown), and the at least one processor may execute a program implemented with at least one computer-readable instructions included in the memory 840.

To this end, the memory 840 may include instructions for, in response to a request received from the user terminal, receiving sensing data of the vehicle linked with the user terminal and requesting the cloud server to provide map information associated with the sensing data of the vehicle. Also, the memory 840 may include instructions for calculating spatial coordinates of the building area including the plurality of pieces of POI information from the map information received from the cloud server and acquiring floor number information for each of the plurality of pieces of POI information on the basis of the spatial coordinates. Also, the memory 840 may include instructions for calculating the reference point of the building area in which the content information related to the plurality of pieces of POI information is to be displayed, on the basis of the sensing data of the vehicle and the floor number information and the spatial coordinates of the building area. Also, the memory 840 may include instructions for performing a rendering request to display AR digital signage corresponding to the content information in a display area determined based on the calculated reference point (i.e., a location in which an AR object is to be rendered). Also, the memory 840 may include instructions for transmitting the result of the rendering request to the user terminal and performing an image correction request to allow the user terminal to map the image of the AR digital signage corresponding to the result of the rendering request to the display area in the driving area acquired through the vision sensor on a floor-by-floor basis.

Meanwhile, the digital signage platform providing apparatus 800 configured to include such a configuration or function may be implemented as a part of a device or system embedded in the vehicle 100, implemented as a separate device or system, or embedded in the user terminal (or the user interface device 200 (see FIG. 7 ) or the navigation system 770).

FIG. 11 is a representative flowchart illustrating an operating method 1100 of a digital signage platform providing apparatus according to an embodiment of the present disclosure.

The operating method 1100 of FIG. 11 may be implemented by a processor provided in the digital signage platform providing apparatus 800 or a processor provided in a user terminal (or a vehicular electronic device or system of a vehicle, a cloud server, etc.) communicatively connected to the digital signage platform providing apparatus 800 and may provide a platform for generating AR digital signage.

Referring to FIG. 11 , first, the operating method 1100 is disclosed as a process of receiving, by the digital signage platform providing apparatus, sensing data of a linked vehicle and transmitting a request for associated map information to the cloud server in response to a request received from the user terminal (1110).

In an embodiment, the map information may include POI information and 2D/3D map information included within a predetermined range based on the current location of the vehicle. In another embodiment, the map information may be a driving image captured through a vision sensor, such as a camera, of the vehicle.

The digital signage platform providing apparatus calculates spatial coordinates of the building area including the plurality of pieces of POI information from the received map information and acquires floor number information for each of the plurality of pieces of POI information (1120).

In other words, when a building including a plurality of POIs is detected or recognized from the map information by the processor of the digital signage platform providing apparatus, the digital signage platform providing apparatus may calculate xyz coordinate information of the building as the spatial coordinates.

In one embodiment, when the map information is 2D/3D map information received from the cloud server, the digital signage platform providing apparatus may receive the information regarding the location, height, and number of floors of the building area including the plurality of pieces of POI information on the basis of the map information and calculate the spatial coordinates of the building area. In another embodiment, when the map information is a driving image acquired through a camera provided in the vehicle, the digital signage platform providing apparatus may estimate the location, height, and number of floors of the building area on the basis of the driving image and estimate the spatial coordinates from the location, height, and number of floors.

In this way, when the spatial coordinates of the building area are calculated, the digital signage platform providing apparatus may calculate or estimate floor number information for each of the plurality of pieces of POI information included in the building area. For example, the digital signage platform providing apparatus may calculate a floor-by-floor height value, i.e., a height offset on the basis of the height and number of floors of the building included in the spatial coordinates of the building area and may compute or estimate the number of floors corresponding to the plurality of pieces of POI information on the basis of the calculated height offset.

Subsequently, the digital signage platform providing apparatus calculates a reference point for displaying content information related to the plurality of pieces of POI information on the basis of the sensing data of the vehicle and the spatial coordinates and floor number information of the building area (1130).

Here, POI-related content information may refer to a brand icon, a 3D model, a still image, or a moving image for POI-related advertisement exposure.

The reference point of the building area for displaying the content information may be calculated by matching the information regarding the vehicle sensing data (the vehicle's driving speed and direction), the spatial coordinates of the building area, and the floor number information of the plurality of pieces of POI information to correspond to the driving image. That is, by using AR technology, the viewpoint of the driving image or the actual driving road (e.g., in the case of an AR navigation device in which AR digital signage is projected on a windshield through a laser sensor) and the content information are matched to the viewpoint of the screen for finding the reference point of the building area for displaying the content information.

In an embodiment, the reference point may be determined as a coordinate point close to the current location among the spatial coordinates of the building area on the basis of the driving direction of the vehicle.

In an embodiment, the display area for each of the plurality of pieces of POI information is obtained by applying a height offset to the floor number information corresponding to the plurality of pieces of POI information with respect to the reference point and is set as a location moved from the reference point by a corresponding floor number+a height offset.

Here, the coordinate point close to the current location of the vehicle may be acquired or estimated by detecting edges of the building identified using coordinate data included in the map information or camera sensing information provided in the vehicle. In this case, a reference point for each piece of content information corresponding to the plurality of pieces of POI information (hereinafter referred to as a “floorwise reference point”) may be set as the reference point+a height offset corresponding to a floor number matched to each piece of POI information. That is, a floorwise reference point is calculated for and applied to each of the plurality of pieces of content information.

The digital signage platform providing apparatus performs an AR rendering request to display AR digital signage corresponding to the content information in a display area determined based on the calculated reference point (1140).

In this regard, the digital signage platform providing apparatus may determine display areas for mapping a plurality of pieces of AR digital signage matched to the plurality of pieces of POI information to corresponding floors of the building.

Specifically, the digital signage platform providing apparatus may determine the display areas of the plurality of pieces of AR digital signage corresponding to the plurality of pieces of POI information using floor number information matched to the plurality of pieces of POI information and height information of the building area calculated based on the spatial coordinates for the building area.

In an embodiment, when the spatial coordinates for the building area cannot be acquired based on the map information, the digital signage platform providing apparatus may determine a display area to which the content information is to be mapped by using floor number information and height information of the building area estimated using the camera sensing information included in the vehicle sensing information.

Meanwhile, according to an embodiment of the present disclosure, the AR rendering request performed by the digital signage platform providing apparatus is performed by an AR engine. The AR engine may be implemented by a processor of the digital signage platform providing apparatus, a processor of the user terminal, a processor of another vehicular electronic device or system of the vehicle, or a cloud server.

When rendering is performed through the AR engine as described above, the digital signage platform providing apparatus transmits a result of the rendering request to the user terminal. Thus, the digital signage platform providing apparatus transmits an image correction request to the user terminal so that the user terminal maps an image of AR digital signage corresponding to the result of the rendering request to a display area of the building in the driving image acquired through the vision sensor on a floor-by-floor basis and then outputs the image (1150).

In an embodiment, the image correction request may be a request for mapping the image of the AR digital signage so that each display area matched to a corresponding piece of content information is moved from the calculated reference point by the height of each piece of floor number information. This will be described in detail below with reference to FIGS. 12 and 13 .

Also, in an embodiment, the image correction request may be a request to map, on a floor-by-floor basis, AR digital signage to a display area that is changed based on the reference point (or a floorwise reference point) and the driving direction and speed of the vehicle. A specific example thereof will be described in detail below with reference to FIGS. 14 and 15 .

FIGS. 12 and 13 are diagrams illustrating a method of arranging AR digital signage on a floor-by-floor basis in a building area of a driving image according to an embodiment of the present disclosure.

The method of arranging AR digital signage on a floor-by-floor in a building area of a driving image may be implemented by a processor of the digital signage platform apparatus according to the present disclosure. Alternatively, as another example, the method may be implemented by a processor of a vehicle display device (e.g., a user interface device, navigation system, or the like provided in a vehicle) including a digital signage platform or may be implemented by a communicatively connected cloud server.

Referring to 12, when a building area 1200 including a plurality of pieces of POI information is detected, the digital signage platform providing apparatus according to the present disclosure may calculate (or estimate) spatial coordinates 1211, 1212, 1213, and P for the building areas on the basis of the map information (e.g., 2D/3D map information, the number of floors of the building area, and height information, etc.) or the driving image acquired through a camera provided in the vehicle.

The digital signage platform providing apparatus may extract an origin P for mapping AR digital signage to the driving image on a floor-by-floor basis by using the sensing data of the vehicle (e.g., a vehicle driving direction), the spatial coordinates 1211, 1212, 1213, and P, and the information on the height and number of floors of the building included in the map information (or estimated through the detection of edges of the driving image).

That is, considering the driving direction 1201 of the vehicle among the spatial coordinates 1211, 1213, 1213, and P of the building area, reference coordinates closest to the location of the vehicle included in the sensing data of the vehicle is set as the origin P.

For example, when the information on the number of floors and height of the building area 1200 can be acquired, the digital signage platform providing apparatus may calculate the origin P considering the driving direction of the vehicle. However, when the map information for the building area 1200 is not present (or is not recognized) or when the information on the number of floors and height cannot be acquired, the digital signage platform providing apparatus may extract the origin of the building area by estimating the number of floors and height of the building from the image of the building using the sensing information of the camera provided in the vehicle and detecting edges of the image. In this case, the height for each floor may use a predefined value.

Meanwhile, in order to display a plurality of pieces of AR digital signage on a floor-by-floor basis, a “floorwise reference point” should be calculated for each of the plurality of pieces of AR digital signage.

In this regard, referring to FIG. 13 , the “floorwise reference point” for each of the plurality of pieces of AR digital signage may be placed by moving the height by the number of floors of the POI information with respect to the origin P and the spatial coordinates 1211, 1212, 1213, and P of the building area. That is, the digital signage platform providing apparatus determines, as a “floorwise reference point,” a location to which a height offset corresponding to the number of floors matched to the origin P+each piece of POI information is applied, and requests correction such that corresponding AR digital signage is mapped to the location.

In FIG. 13 , the reference point of first AR digital signage 1301 displayed on the first floor of the building area 1200 is determined as the origin P. The floorwise reference point of second AR digital signage 1302 displayed on the second floor of the building area 1200 is determined as a point P1 obtained by applying a height offset corresponding to the second floor to the origin P. Also, the floorwise reference points of third AR digital signage and fourth AR digital signage displayed on the third floor and the fourth floor of the building area 1200 are determined as points P2 and P3 obtained by applying the height offsets corresponding to the third floor and the fourth floor to the origin P.

In order to more accurately calculate the height information of the building area, in one embodiment, the digital signage platform providing apparatus may compare the height information (e.g., an interfloor height offset) of each display area determined based on the floorwise reference points and the height information included in the map information (e.g., 2D/3D map information) received from the cloud server and may correct at least one of the location and shape of each display area on the basis of the comparison result. Also, in an embodiment, when the detected difference between the height information and the value of a set of interfloor heights that are initially calculated and the height information of the building area acquired through a database (DB) is greater than or equal to a threshold value (a normal error range), the digital signage platform providing apparatus may correct the location of each display area using the height information of the database (DB).

For example, the digital signage platform providing apparatus may change the interfloor height offset described with reference to FIG. 13 . Alternatively, the digital signage platform providing apparatus may, for example, map a plurality of pieces of AR digital signage 1301, 1302, 1303, and 1304 to the lateral side, not the front side, of the building area 1200 in FIG. 13 on a floor-by-floor basis.

Meanwhile, in an embodiment, the plurality of pieces of AR digital signage 1301, 1302, 1303, and 1304 mapped to the building area 1200 on a floor-by-floor basis surround at least one side of each display area of the building in the driving image. For example, in FIG. 13 , the plurality of pieces of AR digital signage 1301, 1302, 1303, and 1304 are formed to surround the front side of the building area 1200 on a floor-by-floor basis. Accordingly, a plurality of advertisement exposure effects are provided to one building on a floor-by-floor basis, and this gives a realistic feeling as if a real signage signboard is placed on the building.

Example methods of naturally and variably providing images of a plurality of pieces of augmented reality (AR) digital signage by flexibly reflecting various changes in a building's shape based on a driver's viewing angle (or a vehicle's front viewing angle), a vehicle driving situation, a driver's personal tendency, and nearby traffic and structural environments will be described below.

As described above, when AR digital signage such as an actual signage electric signboard is provided on one side of a building area on a floor-by-floor basis, a realistic feeling is further increased. However, since it does not reflect vehicle driving or nearby situations, there is a limitation in that the advertising exposure time for each viewer is short.

In addition, when AR digital signage is always mapped to a specific display area of a building (e.g., the front of a building), the size of the specific display area may decrease or disappear from view depending on the current location and driving direction of the vehicle. In this case, the advertising exposure time of AR digital signage is further reduced.

Furthermore, when the specific display area to which the AR digital signage is mapped is obscured by a structure, the AR digital signage may not be recognized at all. That is, as the visibility of AR digital signage is not secured, the advertising effect is reduced.

FIG. 14 is a diagram illustrating a method of selecting a display area of floorwise AR digital signage on the basis of the shape of a building area according to an embodiment of the present disclosure.

In the present disclosure, the form of a building area or the shape of an image of a building area refers to the shape of the front and lateral sides of the building area varying in real time with respect to a driver's view (or a vehicle's front view) in two dimensions. Also, the shape of the front and lateral sides of the building area may be expressed as numerical information about the front and lateral sides of the building area varying in real time with respect to a driver's view (or a vehicle's front view) in two dimensions.

Here, the driver's view (or the vehicle's front view) may be assumed to coincide with the driving direction of the vehicle. Also, here, the numerical information may include, for example, the areas of the front and lateral sides of the building area, the area ratio, and the distortion ratio.

In an embodiment, the display device 200 according to the present disclosure may determine a display area of AR digital signage on the basis of an image of the building area in the driving image. When the display area is changed based on the shape of the image of the building area, the display device 200 may map the AR digital signage to the changed displayed area and display the mapped AR digital signage.

Here, the determining of the display area based on the image of the building area may refer to the display device 200 determining the display position of floorwise AR digital signage on the side of a building in a driving image acquired through a vision sensor by communication with a system including the above-described digital signage platform providing device 800 and the vehicle 100.

The display position may be one of the front side or the lateral side of the building area. In the present disclosure, the display position may be determined to be more advantageous in securing the visibility of the AR digital signage.

Also, here, the changing of the display area based on the shape of the image of the building area may refer to the display device 200 changing the display position of floorwise AR digital signage from the front side (or the lateral side) of the building in the driving image acquired through the vision sensor to the lateral side (or the front side) or to other nearby locations by communication with a system including the above-described digital signage platform providing device 800 and the vehicle 100.

The changed display position may include other nearby locations outside the building as well as the front side or the lateral side of the building area. In the present disclosure, the changed display position is determined to be a side that is advantageous in securing the visibility of the AR digital signage or to be another position.

To this end, the display device 200 receives, from the vehicle 100, vehicle sensing data including driving-related information (e.g., the driving direction and driving speed of the vehicle, etc.) and information on the driving image acquired through the vision sensor in real time. Also, the display device 200 may deliver the collected data to the digital signage platform providing system so that the digital signage platform providing system can perform data collection, processing, filtering, and merging for displaying the AR digital signage on the determined or changed display area on a floor-by-floor basis and perform an AR rendering request.

Referring to FIG. 14 , for example, while the vehicle is driving, building area A 1410 and building area B 1420 each including a plurality of pieces of POI information in the driving image are displayed on the left and right sides of the driving road. A first plurality of pieces of AR digital signage 1411, 1412, and 1413 are mapped to building area A 1410 on a floor-by-floor basis, and a second plurality of pieces of AR digital signage 1421, 1422, and 1423 are mapped to building area B 1420 on a floor-by-floor basis.

The display areas of the first plurality of pieces of AR digital signage 1411, 1412, and 1413 and the second plurality of pieces of AR digital signage 1421, 1422, 1423 are determined to be positions that are advantageous in securing visibility with respect to the driving direction 1401 of the vehicle.

The first plurality of pieces of AR digital signage 1411, 1412, and 1413 and the second plurality of pieces of AR digital signage 1421, 1422, and 1423 are displayed on display areas that are advantageous in securing visibility on the front and lateral sides of the building areas 1410 and 1412, respectively. For example, the lateral side of building area A 1410 is determined as the display area of the first plurality of pieces of AR digital signage 1411, 1412, and 1413, and the front side of building area B 1420 is determined as the display area of the second plurality of pieces of AR digital signage 1421, 1422, and 1423.

This is because, based on the driving direction 1401 of the vehicle, the lateral side is more advantageous in securing visibility in the case of building area A 1410 and the front side is more advantageous in securing visibility in the case of building area B 1420.

As described above, in the present disclosure, the display device 200 may be operated to determine the display areas on the basis of the image of the building area and change the display areas on the basis of the shape of the image of the building area in order to allow different display sides of each building area in the driving image to be determined as the display areas of the floorwise AR digital signage at the same time.

To this end, the display device 200 according to the present disclosure may determine the display area on the basis of the widths (areas) of the front side and the lateral side in order to determine, as the display area, a position with high visibility in the front and lateral sides of the building area with respect to the driving direction of the vehicle.

In an embodiment, the display device 200 may compare the difference between the widths (areas) of the front side and the lateral side of the building area to a preset critical value and may select one of the front side and the lateral side on the basis of the comparison result. Here, the preset critical value refers to a reference value for determining a display area only by the width size. Accordingly, the display device 200 may be limited to use only widths to determine a display area only when the difference of the widths (areas) of the front side and the lateral side of the building area exceeds the preset critical value.

For example, when the difference between the widths of the front side and the lateral side of the building area exceeds the preset critical value, the display device 200 may select the wider one of the front side and the lateral side of the building area as the display area. On the other hand, when the difference between the widths of the front side and the lateral side of the building area falls below the preset critical value, the display device 200 may determine a preset position (e.g., the front side of the building area) as the display area or may display the display area on the basis of another selection criterion.

In an embodiment, when the difference between the widths (areas) of the front side and the lateral side of the building area falls below the preset critical value, the display device 200 may select one of the front side and the lateral side of the building area as the display area on the basis of the image distortion ratio of the floorwise AR digital signage.

For example, when the difference between the widths of the front side and the lateral side of the building area falls below the preset critical value, the display device 200 may select as the display area one of the front side or the lateral side of the building area for which the image distortion ratio of the floorwise AR digital signage will be smaller. Alternatively, when the difference between the widths of the front side and the lateral side of the building area falls below the preset critical value, the display device 200 may select as the display area one of the front side or the lateral side of the building area for which the distortion ratio of text (font) included in the floorwise AR digital signage will be smaller. Here, the image distortion ratio of the front side and the lateral side of the building area and the distortion ratio of text (font) included in the floorwise AR digital signage may be calculated after a predetermined weight is assigned to each image.

In FIG. 14 , the first plurality of pieces of AR digital signage 1411, 1412, and 1413 are mapped to display areas of the lateral side of building area A 1410 in which the difference between the widths (areas) of the front side and the lateral side of the building area falls below the preset critical value and in which the image distortion ratio of the floorwise AR digital signage is smaller.

Also, in FIG. 14 , the second plurality of pieces of AR digital signage 1421, 1422, and 1423 are mapped to display areas of the front side of building area B 1420 in which the difference between the widths (areas) of the front side and the lateral side of the building area exceeds the preset critical value and which has a greater width than the lateral side.

As described above, the display device 200 according to the present disclosure may determine the display area of the image of the floorwise AR digital signage on the basis of the image of the building area in the driving image acquired through the vision sensor by communication with the vehicle 100 and the digital signage platform providing system. Also, the display device 200 according to the present disclosure may change the display area on the basis of the shape of the image of the building area in the driving image acquired through the vision sensor, transmit information on the changed display area to the digital signage platform providing system, and receive a rendering result or related information for mapping an image of the AR digital signage corresponding to the changed display area from the corresponding system.

Also, in an embodiment, a processor of the display device according to the present disclosure may change the display area on the basis of the image distortion ratio of the building area recognized through the camera of the vehicle. In this case, by transmitting the information on the changed display area to the digital signage platform providing system, the display device may receive the rendering result or related information for displaying the AR digital signage on the changed display area on a floor-by-floor basis.

FIG. 15 is a diagram illustrating a method of selecting a display area of floorwise AR digital signage on the basis of vehicle driving information according to an embodiment of the present disclosure.

In the present disclosure, even after the display area is determined and the AR digital signage is displayed on a floor-by-floor basis, the display device may calculate the widths of the front side and the lateral side of the building area changing along with the driving of the vehicle, change the display area on the basis of the calculation result, and map the floorwise AR digital signage to the changed display area. This provides an advantageous effect of securing the visibility of AR digital signage in real time.

As described above, in order to calculate the widths of the front side and the lateral side of the building area changing along with the driving of the vehicle, the display device 200 according to the present disclosure may calculate the widths on the basis of the change in shape of the image of the front side and the lateral side of the building acquired through the vision sensor of the vehicle.

In FIG. 15 , as shown in 15A, at the beginning (at a first time point), a plurality of pieces of AR digital signage 15111, 1512, and 1513 are mapped and displayed using the lateral side of the building area in the driving image as the display area. As described above with reference to FIG. 14 , since the difference between the widths A and B of the front side and the lateral side of the building area is less than or equal to the preset critical value on the basis of the current location and the driving direction 1501 of the vehicle at the first time point, the lateral side, which has a smaller image distortion ratio, is determined as the display area.

Subsequently, when the vehicle approaches the building area (a second time point after the first time point) as the vehicle is driving, as shown in FIG. 15B, the display area is changed to the front side of the building area in the driving image, and a plurality of pieces of AR digital signage 1521, 1522, and 1523 are mapped and displayed. That is, although the display area has been determined once, the display device 200 changes the display area itself from the lateral side to the front side beyond mapping the plurality of pieces of AR digital signage 1511, 1512, and 1513 according to the image of the display area of the lateral side varied along with the driving of the vehicle.

Since the difference between the widths A″ and B″ of the front side and the lateral side of the building area exceeds the preset critical value on the basis of the current location and the driving direction 1502 of the vehicle at the second time point, the front side, which is a greater width, may be determined as the display area.

In an embodiment, the processor of the display device 200 according to the present disclosure may change the display area to which the image of the floorwise AR digital signage is to be mapped on the basis of the sensing data of the vehicle received while the vehicle is driving.

For example, as described above with reference to FIG. 15 , the display device 200 may receive the sensing data of the vehicle (e.g., the current location and driving direction of the vehicle) in real time and monitors whether the difference between the widths of the front side and the lateral side of the same building area exceeds the preset critical value.

When the monitoring result is that the difference between the width values exceeds the preset critical value, the side that has a greater width at the current time may be displayed as the display area. In this case, when the floorwise AR digital signage is currently displayed on the side that has a smaller width, the display area may be changed. On the other hand, when the monitoring result is that the difference between the widths is less than or equal to the preset critical value, the one of the front side and the lateral side that has a smaller image distortion ratio (e.g., the side that has a smaller aspect ratio (height offset) difference) is determined as the display area. In this case, when the floorwise AR digital signage is currently displayed on the side having a larger image distortion ratio, the display area may be changed.

In an embodiment, when the areas of the front side and the lateral side of the building area in the driving image acquired through the vision sensor change along with the driving of the vehicle, the processor (or the control unit) of the display device 200 according to the present disclosure may transmit information on the change in the areas to the digital signage platform providing system. Here, the information on the change in the areas may include, for example, information related to the change of the display area such as the difference between the widths of the front side and the lateral side of the building area, the result of comparing the difference between the widths to the critical value, and the image distortion ratios of the front side and the lateral side.

Also, in an embodiment, the processor of the display device 200 may receive a result of a rendering request for generating AR digital signage on the basis of the information on the change in the areas and may change the display area of the floorwise AR digital signage from one side of the building area in the driving image to another side and then perform mapping.

In an embodiment, the processor of the display device 200 may map the floorwise AR digital signage while gradually moving the floorwise digital signage from one side of the building area in the driving image to another side according to the driving direction and driving speed of the vehicle.

For example, referring to FIG. 15 , when it is determined that the display area is changed from the lateral side to the front side, the first plurality of pieces of AR digital signage 1511, 1512, and 1513 that have been displayed on a floor-by-floor basis on the lateral side of the building may gradually move toward the front side along with the driving of the vehicle as shown in FIG. 15A and may be seamlessly moved and then displayed on the front side of the building after a certain period of time as shown in FIG. 15B. Thus, an antipathy to the display of the second plurality of pieces of AR digital signage 1521, 1522, and 1523 is minimized, and the advertising exposure time is increased as the digital signage is moved along the driving direction of the vehicle.

Meanwhile, according to the present disclosure, when AR digital signage is displayed on a building of a driving image on a floor-by-floor basis, a realistic feeling is further increased like real signage. However, as a vehicle approaches the building, the building and the signage mapped to the building deviate from the driving image, and thus visibility is reduced.

However, when a vehicle enters a building including a plurality of pieces of POI information or when a destination POI is located in a building, the need for floorwise AR digital signage is further increased. Accordingly, a method of providing differentiated floorwise AR digital signage while a vehicle approaches a building area including a plurality of pieces of POI information and enters or is expected to enter the corresponding building area will be described in detail below.

In the present disclosure, a situation in which a vehicle enters a building area may be determined based on sensing data of the vehicle including the current location of the vehicle, the distance between the vehicle and the corresponding building area, and the driving speed of the vehicle. For example, when the vehicle approaches the corresponding building area and reduces the driving speed without situations such as waiting for a light change or finding an obstacle, this may be determined as a situation in which the vehicle enters the building area.

In the present disclosure, a situation in which a vehicle is expected to enter a building area may be determined based on the current location of the vehicle, the distance between the vehicle and the corresponding building area, whether a destination or waypoint POI is included in the building area, the specificity of the building area, whether a user's preferred band or POI is included, and the like.

In the present disclosure, the case in which conditions for allowing a vehicle to enter a building area are satisfied may refer to a situation in which the vehicle enters the building area and/or a situation in which the vehicle is expected to enter the building area. In the present disclosure, whether the conditions for allowing a vehicle to enter a building area are satisfied may refer to determining whether the vehicle enters the building area and/or whether the vehicle is expected to enter the building area.

In the present disclosure, an AR carpet refers to an AR object that is mapped as if a thin layer of carpet is laid in a certain range of a road/sidewalk/floor in a driving image. The AR carpet may be implemented to have a transparency equal to a certain value or a predetermined texture, pattern, or the like so that the area of the mapped road/sidewalk/floor can be seen transparently and then may be mapped.

FIG. 16 is a diagram illustrating a method of mapping floorwise AR digital signage to an AR carpet rather than to a building according to an embodiment of the present disclosure.

In the present disclosure, a display device 200 linked to a vehicle (e.g., a center information display (CID), a cluster, a head-up display (HUD), a rearview mirror display, a rear seat entertainment (RSE), and a display device or terminal that projects driving images onto the vehicle's windshield or dashboard) may map and display floorwise AR digital signage on a driving image projected or acquired through a vision sensor (e.g., a camera, an imaging laser sensor, etc.) of the vehicle.

To this end, a processor of the display device 200 may communicate with the vehicle and the digital signage platform providing system and may transmit a request to the corresponding system for generating the AR digital signage on a floor-by-floor basis. Also, the processor of the display device 200 may receive a result of the request from the system and may map and display corresponding AR digital signage on a building area in the driving image on a floor-by-floor basis. To this end, the processor of the display device 200 may be implemented to include an AR engine or perform the same function as an AR engine.

Referring to FIG. 16 , the display device 200 may map and display a plurality of pieces of AR digital signage 1611, 1612, and 1613 on one surface of a building 1610 in a driving image 1601 acquired through the vision sensor of the vehicle on a floor-by-floor basis.

To this end, the display device 200 may communicate with the vehicle to receive the sensing data of the vehicle, for example, the current location of the vehicle, driving-related information of the vehicle, and the like. Also, the display device 200 may communicate with the digital signage platform providing system 1000 (see FIG. 27 ) to transmit the sensing data of the vehicle, receive associated POI information, for example, the spatial location of the building including a plurality of pieces of POI information and floor number information, and receive traffic-related information of the vehicle from a cloud.

The display device 200 may recognize at least the spatial location of the building area including the plurality of pieces of POI information on the basis of the received information.

The display device 200 may transmit, to the system 1000, a request for generating AR digital signage corresponding to content information related to the plurality of pieces of POI information on a floor-by-floor basis (hereinafter referred to as a first request) using the sensing data of the vehicle, the spatial location of the building area, and the floor number information. Also, the display device 200 may receive the results of collection, processing, filtering, and matching of data corresponding to the request from the system 1000 and may map and display AR digital signage on the building in the driving image on a floor-by-floor basis.

The display device 200 may transmit, to the system 1000, a request for generating an AR carpet for guiding entry into the building in the driving image (hereinafter referred to as a second request) on the basis of the driving-related information included in the sensing data of the vehicle. Also, the display device 200 may receive the results of collection, processing, filtering, and matching of data corresponding to the request from the system 1000 and may map and display an AR carpet on the road in the driving image.

In this case, the mapping position of the AR carpet may be determined based on the current location of the vehicle. For example, the AR carpet may be mapped and displayed in the range of 2 to 10 m ahead of the current location of the vehicle and the road lane in which the vehicle is traveling.

In an embodiment, the display device 200 may transmit the first request and the second request simultaneously or sequentially. Also, the display device 200 may receive the results of the first request and the second request from the system 1000 simultaneously or sequentially. Also, the display device 200 may map and display AR objects (e.g., floorwise AR digital signage and AR carpet) corresponding to the received result according to the current locations of the vehicle and the building area and whether predetermined conditions are satisfied, irrespective of the order in which the results of the first and second requests are received.

Referring to FIG. 16 , when the vehicle approaches the building 1610 and at least one of the plurality of pieces of POI information included in the corresponding building 1610 is set as a destination POI 1630, the processor of the display device 200 may determine this case as the situation in which the vehicle is about to enter the building 1610 or the situation in which the vehicle is expected to enter the building 1610.

In this case, the processor of the display device 200 may map and display the AR carpet 1620 for guiding entry into the building 1610 to the road 1602 in the driving image 1601 on the basis of the result of the request for generating the AR carpet received from the linked digital signage system.

When the AR carpet 1620 is mapped and displayed on the road 1602 in the driving image 1601, the processor of the display device 200 may monitor, for a certain time (e.g., within one or two, or more, seconds), whether there is a change in the situation in which the vehicle is about to enter the building 1610 or the situation in which the vehicle is expected to enter the building 1610.

When the monitoring result is that there is no change in the situation in which the vehicle is about to enter the building 1610 or the situation in which the vehicle is expected to enter the building 1610, the processor of the display device 200 changes the AR carpet 1620 to a display area and maps and displays the plurality of pieces of AR digital signage 1621, 1622, and 1623 on the AR carpet 1620. In this case, the plurality of pieces of AR digital signage 1611, 1612, and 1613 that have been displayed on the front of the building 1610 on a floor-by-floor basis may be resized and displayed continuously (e.g., with a size smaller than the front surface of the building 1610) or may disappear.

When the monitoring result is that the situation in which the vehicle enters the building 1610 or the situation in which the vehicle is expected to enter the building 1610 is changed (e.g., when the vehicle proceeds past the building 1610), the processor of the display device 200 may operate so that the AR carpet 1620 is no longer displayed on the road 1602 in the driving image 1601. This is because it is no longer necessary to guide the entry of the vehicle.

In an embodiment, the AR digital signage mapped and displayed on the AR carpet 1620 may be limited to some of the plurality of pieces of AR digital signage 1621, 1622, and 1623. For example, although not shown, the mapped and displayed AR digital signage may be limited to only AR digital signage corresponding to floorwise representative POI information, or the maximum number of pieces of AR digital signage to be displayed on the AR carpet 1620 (e.g., less than five or a number smaller than the number of floors of the building 1610) may be preset.

The AR carpet 1620 may include visual information (e.g., an arrow image) for guiding entry into the building 1610. For example, when the building 1610 includes a destination POI in FIG. 16 , the AR carpet 1620 may be implemented and mapped to include an indication for the destination POI 1630 and visual information (e.g., an arrow image) for guidance to a parking lot of the building 1610.

The plurality of pieces of AR digital signage 1621, 1622, and 1623 mapped on the AR carpet 1620 may be sequentially displayed on floorwise display areas (i.e., the AR carpet 1620) of the building 1610 on the basis of the current location of the vehicle and driving direction. For example, in FIG. 16 , the first AR digital signage 1621, the second AR digital signage 1622, and the third AR digital signage 1623 may be mapped and displayed according to the driving direction of the vehicle as if they are spread (layered) on the AR carpet 1620 according to the floor order of the floorwise AR digital signage of the building 1610. This is different from the above-described method in which the floorwise AR digital signage is mapped and displayed on the front or side of the building as if it were erected in the vertical direction of the building.

As described above, the display device according to the present disclosure is implemented to map and display an AR carpet and a plurality of pieces of AR digital signage on a road in a driving image rather than on a building in order to secure the visibility of the advertisement signage in the situation in which the vehicle is about to enter the building or the situation in which the vehicle is expected to enter the building. Also, visual information can be provided to a road ahead without a driver having to change his or her gaze to the building to see the destination POI, and this helps safe driving.

FIG. 17 is a flowchart illustrating a method of mapping floorwise AR digital signage to an AR carpet in a diving image acquired through a vision sensor according to an embodiment of the present disclosure. A display device linked to a vehicle according to the present disclosure may perform the following operations by at least one processor.

Referring to FIG. 17 , the processor of the display device according to the present disclosure is connected to a digital signage platform providing system (hereinafter, referred to as a system) through a communication module to transmit a request for POI information associated with the sensing data of the vehicle (1710). To this end, the display device is linked to the vehicle to receive the sensing data of the vehicle from a vehicular electronic device, an advanced driver assistance system (ADAS) sensor, or other systems and provide the sensing data to the system.

Subsequently, the processor of the display device recognizes a spatial location of a building area including a plurality of pieces of POI information on the basis of the POI information received from the system (1720). Here, the spatial location may refer to x-, y-, and z-coordinate information of a building including the plurality of pieces of POI information. In an embodiment, the spatial location may be transmitted together with the POI information from the system and/or a cloud linked to the system.

Subsequently, the processor of the display device transmits, to the system, a first request for generating AR digital signage corresponding to content information related to the plurality of pieces of POI information on a floor-by-floor basis using the sensing data of the vehicle, the spatial location of the building area, and the floor number information (1730).

Here, the sensing data of the vehicle may include the current location of the vehicle, driving-related data (e.g., the driving speed, the driving direction, a brake signal, a danger signal, and the like, of the vehicle) acquired through GPS and ADAS sensors of the vehicle, and data related to the driving image acquired through the vision sensor of the vehicle. Also, the floor number information of the building area may be received from the system or may be received from the cloud linked to the system.

Here, the first request may include a request for causing the system to collect, process, filter, and match various data to generate the AR digital signage on a floor-by-floor basis and for causing the system to transmit the result so that the processor of the display device can perform AR rendering based on the result. In this case, by mapping, in real time, an AR object (here, floorwise AR digital signage) corresponding to the result on the driving image acquired through the vision sensor of the vehicle, the processor of the display device may display the floorwise AR digital signage on the building.

In an embodiment, the first request may include a command to extract floorwise representative POI information of the building area. For example, when a plurality of pieces of POI information are included in one layer, the processor of the display device may make a request to select representative POI information to implement AR digital signage of the corresponding layer on the basis of a smaller number (e.g., one) of pieces of POI information. In this case, the selection of the representative POI information may be made based on user preference, brand recognition, service class, and the like.

In an embodiment, the first request may be performed based on a user input to the display device. The user input may include various types of user inputs, such as a touch input to the touch screen of the display device, an input to a specific key (a hard key or a soft key), a voice command input, a gesture input, and the like.

Subsequently, the processor of the display device may transmit, to the system, a second request for generating an AR carpet for guiding entry into the building area in the driving image on the basis of the driving-related information included in the sensing data of the vehicle.

Here, the driving-related information included in the sensing data of the vehicle may include, for example, the driving speed of the vehicle, the lane of the vehicle, and information related to a waypoint/destination included in a driving guidance route.

In an embodiment, the first request may be transmitted to the system as long as a building area including a plurality of pieces of POI information is detected, and the second request may be performed when a present condition (referred to as a second condition) is satisfied after the first request is transmitted (referred to as a first condition). Here, the second condition may be a condition associated with the driving-related information included in the sensing data of the vehicle. For example, when the building area including the plurality of pieces of POI information is detected, the display device may operate to transmit the first request to the system and then transmit the second request when the distance between the vehicle and the corresponding building area is within a certain range and the driving speed is reduced to a certain range.

Subsequently, the display device receives results corresponding to the first and second requests from the system through the communication module (1750). Here, the results corresponding to the first and the second requests may be received simultaneously or sequentially. However, even if the first and second requests are sequentially received, the order in which corresponding AR objects (e.g., the floorwise AR digital signage and the AR carpet) are displayed may vary. For example, even if the result corresponding to the first request is received before the result corresponding to the second request, the AR carpet corresponding to the first request may be displayed first in the driving image.

After the results corresponding to the first and second requests are received, the processor of the display device determines whether conditions for allowing the vehicle to enter the building area are satisfied. Also, based on the result, the processor of the display device may display the AR carpet corresponding to the result of the second request on the road in the driving image acquired through the vision sensor of the vehicle as a display region and may map at least a portion of the floorwise AR digital signage corresponding to the result of the first request to the display area.

In an embodiment, the display device may map and display, by using the process, floorwise AR digital signage corresponding to the result of the first request in the display area of the building area in floor order on the basis of the location and driving direction of the vehicle.

Here, the display area may be changed depending on whether conditions for allowing the vehicle to enter the building area are satisfied. Specifically, when the conditions for allowing the vehicle to enter the building area are not satisfied (e.g., when the vehicle is at least a certain distance away from the building, when it is confirmed that the vehicle will not enter the building, or that the vehicle is not expected to enter the building, etc.), the display area may be set as the front/side of the building in the driving image. However, when the conditions for allowing the vehicle to enter the building area are satisfied, the display area may be an AR carpet mapped on the road in the driving image.

In an embodiment, whether the conditions for allowing the vehicle to enter the building area are satisfied may be determined based on at least one of the current location of the vehicle, the driving-related information of the vehicle, the characteristics of the building area, the correlation between the building area and the destination, and user preference.

For example, when the driving speed decreases while the current location of the vehicle becomes close to the building area, the processor of the display device may determine that the conditions for allowing the vehicle to enter the building area are satisfied.

Alternatively, for example, when the destination of the vehicle is set at a relatively remote distance (e.g., it takes more than 2 hours to arrive at the destination) and the building area includes the characteristics of convenience facilities such as a parking lot, a rest area, a gas station, etc., the processor of the display device may determine that the conditions for allowing the vehicle to enter the building area are satisfied.

Alternatively, for example, when it is detected based on the sensing data of the vehicle that vehicle inspection is required due to insufficient gasoline or air pressure reduction and the building area includes facilities such as a gas station/service station, the processor of the display device may determine that the conditions for allowing the vehicle to enter the building area are satisfied.

Alternatively, for example, when a building area including POI information such as a preferred brand, a frequently visited place, or a popular place (e.g., selected by many other users), that are set by a driver/user is detected at a location near the current location of the vehicle, the processor of the display device may determine that the conditions for allowing the vehicle to enter the corresponding building area are satisfied.

Meanwhile, in an embodiment, the floorwise AR digital signage may be mapped and displayed on the building in the driving image on a floor-by-floor basis while the conditions for allowing the vehicle to enter the building area are not satisfied. When the conditions are satisfied, the floorwise AR digital signage may be moved and mapped to the AR carpet.

Specifically, the processor of the display device according to the present disclosure maps and displays an image of the floorwise AR digital signage corresponding to the result of the first request on the building in the driving image on a floor-by-floor basis. Subsequently, when it is detected, based on the sensing data of the vehicle, that the vehicle approaches within a certain range from the building area and the driving speed of the vehicle is less than or equal to a threshold range, the AR carpet may be displayed as a guidance route in the driving image. Subsequently, when a result of monitoring for a predetermined time (e.g., 1 to 2 seconds) shows that the entry of the vehicle is more confidently predicted, the processor of the display device considers that the conditions for allowing the vehicle to enter the corresponding building area are satisfied and maps and displays the floorwise AR digital signage on the AR carpet at regular intervals in the driving direction.

As described above, according to the present disclosure, when the conditions for allowing the vehicle to enter the building area are satisfied as described above, the floorwise AR digital signage may be displayed differently from the conventional method of mapping and displaying AR digital signage on a building on a floor-by-floor basis, in order to enhance visibility. Specifically, by displaying the AR carpet that guides entry into the corresponding building area on the road in the driving image and sequentially displaying AR digital signage on a floor-by-floor basis, it is possible to satisfy both visibility and driver convenience along with floorwise signage guidance.

FIGS. 18, 19, 20, and 21 are diagrams illustrating that AR digital signage that has originally been displayed on a building on a floor-by-floor basis, is thereafter mapped on an AR carpet of a road as a vehicle approaches a building area according to an embodiment of the present disclosure.

Specifically, FIGS. 18 to 21 sequentially disclose an example of changing an AR carpet according to the driving of a vehicle and a plurality of pieces of AR digital signage mapped to the AR carpet in a situation where the vehicle is about to enter a building.

First, referring to FIG. 18 , the display device 200 according to the present disclosure maps and displays a plurality of pieces of AR digital signage 1811, 1812, and 1813 on one surface of a building 1810 in a driving image acquired through a vision sensor of the vehicle on a floor-by-floor basis, and thus realistic advertisement signage is provided to a driver.

In this case, each piece of the AR digital signage 1811, 1812, and 1813 may be composed of a floorwise representative POI. Also, the content may include an advertisement, a brand, or news information related to the representative POI for each layer, and each piece of content may be implemented as an AR object in the form of a brand icon, a 3D model, a still image, or a video image.

When the corresponding building 1810 includes POI information such as a destination/waypoint, a POI indication 1830 may be displayed in the driving image.

When the corresponding building 1810 includes POI information such as a destination/waypoint and the vehicle drives to the location of the POI indication 1830, the display device 200 may determine that the conditions for allowing the vehicle to enter the building 1810 are satisfied.

In this case, as shown in FIG. 19 , the display device 200 may map and display an AR carpet 1920 that guides entry into a building 1910 on a road 1902 in the driving image. The AR carpet 1920 may be implemented to include information on guidance to the location of the POI indication 1830 (or the location of a parking entrance) from the current location of the vehicle in the driving direction.

In an embodiment, when the vehicle approaches within a certain range from the building 1910 and the driving speed of the vehicle is less than or equal to a threshold range, the display device 200 may display the AR carpet as a guidance route in the driving image.

As described above, when the vehicle drives toward the POI indication 1830, the distance between the vehicle and the building 1910 becomes closer, and accordingly, some of the plurality of pieces of AR digital signage 1811, 1812, 1813 displayed on the building 1910 may become out of the field of view of the driving image together with the surface of the building 1910 on which the AR digital signage was displayed. In this case, the advertisement effect can be reduced due to reduced visibility, and also a dangerous situation may occur in which a driver changes his or her gaze from the front of the vehicle to the building to see the destination POI.

Thus, in an embodiment, as the vehicle approaches the building area, the processor of the display device 200 may gradually reduce AR digital signage that has been displayed on the building of the driving image on a floor-by-floor basis and map and display resized AR digital signage suitable for viewing by the driver in this situation. For example, as shown in FIG. 19 , a plurality of resized (or reduced) pieces of AR digital signage 1911, 1912, and 1913 are displayed on the building 1910. In this case, although a realistic feeling is reduced compared to before, this can help to secure visibility and driving safety.

In an embodiment, a rate at which the AR digital signage is resized may be determined based on the distance between the building and the vehicle. For example, as the distance between the vehicle and the building decreases, the AR digital signage may be correspondingly reduced. In this case, the amount of information or content type included in the resized AR digital signage may also be changed.

In still another embodiment, the shape or form of the AR digital signage may be changed as the vehicle approaches the building area. For example, the floorwise AR digital signage is displayed while the distance between the vehicle and the building is greater than or equal to a predetermined value, and the floorwise AR digital signage may be reshaped to a simple AR object such as a symbol or an icon when the distance is less than the predetermined value.

Subsequently, as shown in FIG. 20 , when it is determined that the vehicle approaches a destination POI indication 1930 or conditions for allowing the vehicle to enter the building area are maintained for a certain period of time, the processor of the display device 200 may move and map floorwise AR digital signage 2021, 2022, and 2023 on the AR carpet 1920 that guides entry to the building 1910.

To this end, the display device 200 may transmit a rendering request to the system 1000 (FIG. 27 ) so that the image of the floorwise AR digital signage moves from the building 1910 to the AR carpet 1920 at a certain time after the AR carpet is displayed. In this case, the rendering request may be a request for collecting, processing, filtering, and merging data for generating a plurality of pieces of AR digital signage to be mapped on the AR carpet 1920.

Subsequently, the display device 200 may receive a result of the request from the system 1000 and map and display the floorwise AR digital signage 2021, 2022, and 2023 on the AR carpet 1920. In this case, the result of the request may refer to a result of the system 1000 collecting, processing, filtering, and merging the data.

In FIG. 20 , the plurality of pieces of AR digital signage 2021, 2022, and 2023 displayed on the AR carpet 1920 may be connected and mapped and may include corresponding floor number information (e.g., 1F, 2F, and 3F) indicating the floor location within the building. Also, although not shown, in another embodiment, the plurality of pieces of AR digital signage 2021, 2022, and 2023 may not be laid on the AR carpet 1920 but may be mapped in different forms within the driving image (e.g., a signboard form, a hovering form, etc.). However, in consideration of safe driving and the appearance of other obstacles on the road, the shape change may be restricted within a range that does not significantly obscure the road image in the driving image.

Subsequently, as shown in FIG. 20 , while the AR digital signage is displayed on the AR carpet 1920, a plurality of pieces of AR digital signage 2011, 2012, and 2013 may be displayed in a variable form on the building 1910 of the driving image, may be no longer displayed, or may be displayed as highlighted images. Thus, the driver may immediately recognize that AR information currently being displayed on the AR carpet 1920 is in reference to the building 1910.

Next, as the vehicle approaches the entry point of the building 1910, that is, the destination POI indication 1930, the display device 200 may map and display only the AR digital signage 2111 corresponding to the destination POI information on a changed AR carpet 1920′. That is, when the entry of the vehicle is more certain, e.g., based on the vehicle's proximity, the information may be more intuitively provided to the driver by providing only advertisement signage related to the destination POI information.

Meanwhile, the changed AR carpet 1920′ may include a reduction in the width of the carpet image as shown in FIG. 21 . However, the present disclosure is not limited thereto, and the AR carpet 1920 may be changed by an increase in the transparency of the carpet image or by another shape of entry guidance indication (e.g., a solid line, a dotted line, etc.) to be distinguished from a lane.

FIG. 22 is a diagram illustrating that AR digital signage corresponding to destination POI information is highlighted and mapped and displayed on an AR carpet according to an embodiment of the present disclosure.

As described above, when it is more certain that a vehicle is about to enter a building, displaying advertisement signage on the building may not only reduce visibility but also interfere with safe driving. This can be addressed by displaying an AR carpet on the road in front of the vehicle and mapping AR digital signage on the AR carpet. Meanwhile, FIG. 22 presents a method of changing AR digital signage to more intuitively provide information to the driver in a situation in which the entry of the vehicle to the building has become more certain.

Accordingly, according to the present disclosure, when it becomes more certain that the vehicle is about to enter the building, the AR carpet is reduced in size, and the image of AR signage of a floor corresponding to the destination POI information and the images of AR signage of other floors may be visually distinctly mapped to the changed display area. In this case, the degree to which the AR carpet is reduced in size may vary based on the distance between the building and the current location of the vehicle or the degree to which the vehicle enters the building.

As shown in FIG. 22A, the AR carpet 1920′ is displayed in a reduced size in a situation in which the entry of the vehicle to the building 1910 becomes more certain. Meanwhile, the AR digital signage 2111 corresponding to the destination POI information is displayed in an enlarged size so that the AR digital signage 2111 can be intuitively seen by the driver. At this time, the AR digital signage 2112 and 2113 corresponding to the representative POI information of different layers is displayed in a reduced size. Accordingly, the AR digital signage 2111 corresponding to the destination POI information is made more conspicuous.

In another embodiment, as shown in FIG. 22B, the AR digital signage 2111 corresponding to the destination POI information is displayed in an enlarged size, and AR digital signage corresponding to representative POI information of some other layers may be hidden. Accordingly, the driver can visually recognize information on the destination POI more quickly.

Meanwhile, although not shown, in another embodiment, the plurality of pieces of AR digital signage 2111, 2112, and 2113 may be hidden or become transparent sequentially from the lowest layer while the vehicle is entering the building 1910 in a situation in which the entry of the vehicle to the building 1910 is more certain. In this case, the AR digital signage 2111 corresponding to the destination POI information may be highlighted. Also, the corresponding floor number of the building 1910 may also be highlighted.

Also, in an embodiment, the display range of the AR carpet 1920′ may be gradually reduced based on the distance between the vehicle and the destination POI and the driving speed of the vehicle.

In another embodiment, the AR digital signage 2111 corresponding to the destination POI information may be continuously highlighted and displayed on the road and the building (e.g., the corresponding floor number region) in the driving image even while the vehicle is entering the building.

FIGS. 23 and 24 are diagrams illustrating different methods of changing the display of an AR carpet and AR digital signage when an obstacle is on a road, according to an embodiment of the present disclosure.

As described above, when conditions for allowing the vehicle to enter the building are satisfied and thus AR digital signage for the building is mapped on the road of the driving image, visibility is greatly secured. However, exceptionally, when an obstacle appears ahead in the driving direction of the vehicle, the obstacle may interfere with safe driving. Here, examples of how to handle such an exceptional situation will be described.

When an obstacle is detected in the display area of the AR carpet in the driving image acquired through the vision sensor of the vehicle, the processor of the display device 200 according to an embodiment of the disclosure maps and displays the AR carpet and the floorwise AR digital signage so that the detected obstacle can be recognized by changing the transparency of the images of the AR carpet and the floorwise AR digital signage.

To this end, the display device 200 may increase the transparency of the images of the floorwise AR digital signage and the AR carpet being currently displayed, by receiving the sensing data of the vehicle, recognizing the appearance of an obstacle near (in front of and to the sides of) the vehicle, and delivering the related information to the processor. Thus, the driver can more reliably recognize the presence and location of the obstacle that has appeared.

The presence and location of the obstacle may be recognized through sensors of the vehicle linked to the display device 200, for example, an ADAS sensor, a front sensor, etc.

For example, referring to FIG. 23A, while an AR carpet 2320 is mapped and displayed on a road in the driving image of the vehicle and a plurality of pieces of AR digital signage 2321 and 2322 associated with a building including a destination POI 2330 are displayed, a person may pass in front of the vehicle (e.g., at a traffic light crossing).

In this case, the display device 200 may receive sensing data corresponding to a signal sensed through a sensor provided in the vehicle and may map and display a plurality of pieces of AR digital signage 240 and an AR carpet with an increased transparency, as shown in FIG. 23B.

For example, when the previous transparency of the plurality of pieces of AR digital signage and the AR carpet is set to about 60%, the transparency may be increased to more than 80% in the situation shown in FIG. 23B. Accordingly, the driver can more reliably recognize a person who crosses at a pedestrian crossing and perform safe driving.

In another embodiment, the display device 200 may receive the sensing data of the vehicle, recognize the appearance of an obstacle near (in front of and to the sides of) the vehicle, deliver related information to the processor, and move and map the floorwise AR digital signage that has been displayed on the AR carpet to another location.

For example, as shown in FIG. 24A, while the AR carpet 2320 is mapped and displayed on a road in the driving image of the vehicle and a plurality of pieces of AR digital signage 2321 and 2322 associated with the building including the destination POI 2330 are displayed, the AR digital signage 2341 and 2342 may be changed and mapped in the form of signboards as shown in FIG. 24B when a person appears in front of the vehicle. In this case, the changed AR digital signage 2341 and 2342 may be mapped and displayed on adjacent locations off the road (e.g., a boundary area between the road and the sidewalk). Also, the AR carpet 2320 may not be displayed on the road in the driving image while an obstacle is detected.

In this way, when the appearance of an obstacle is detected in the driving direction of the vehicle, the driver may reliably recognize the obstacle and drive safely by stopping the display of the AR carpet and moving and mapping the image of the floorwise AR digital signage to another display area in the driving image.

Meanwhile, although not shown, the AR digital signage may be mapped and displayed on the AR carpet with a preset transparency once again at a certain time after an obstacle is no longer detected in front of or in the driving direction of the vehicle on the basis of the sensing data of the vehicle.

FIGS. 25 and 26 are diagrams illustrating a method of mapping and displaying related AR digital signage on an AR carpet that guides a lane change as the lane change is performed while the AR carpet is displayed, according to an embodiment of the present disclosure. This embodiment is an expanded application of the above discussion of whether the conditions for allowing the vehicle to enter a building are satisfied.

In the present disclosure, whether the conditions for allowing the vehicle to enter the building area are satisfied may be determined based on at least one of the current location of the vehicle, the driving-related information of the vehicle (e.g., a driving direction, a driving speed, and gasoline/charging gauge information of the vehicle), the characteristics of the building area itself, the correlation between the building area and the destination, and user preference.

Here, the characteristics of the building area itself may refer to a place including a POI or a building having a special purpose related to the movement of the vehicle. For example, the place may include places related to the maintenance, rest, and parking of the vehicle, such as a gas station, a vehicle repair shop, a rest area, and a public parking lot.

Also, the correlation with the destination may include not only the building including the destination POI information but also places or buildings frequently visited during the driving to destinations and buildings with specific brands. Also, when the set destination is a long distance from the current location of the vehicle, a rest area, a gas station, etc. may be included as buildings correlated with the destination.

Also, the user preference may include places or buildings including POI information, building information, or specific brands that are preset by the user or places selected by many people (e.g., popular places).

Referring to FIG. 25 , a building area (e.g., a rest area, a gas station, etc.) that satisfies the conditions for allowing the vehicle to enter the building may be detected on a preset driving route of the vehicle even though there are currently no buildings visible in the driving direction of the vehicle, based on the correlation with the destination, the characteristics of the building area itself, and user preferences. At this time, it may be necessary to change the driving of the vehicle in order to enter the detected building area. Here, the lane change of the vehicle will be described as an example.

For example, when the vehicle should change the current driving lane 2501 to the right lane 2502 so as to enter the corresponding building area, the display device 200 may map and display an AR carpet 2510 that guides a lane change on the current driving lane 2501 in the driving image acquired through the vision sensor of the vehicle. In this case, the AR carpet 2510 may include visual information for guiding the driver to change lanes from the current driving lane 2501 to the right lane 2502 (e.g., an arrow image toward the right lane 2502).

When the driver changes lanes to the right lane 2502 in response to the display of the AR carpet 2510, the lane change may be detected through the sensing data of the vehicle. Accordingly, as shown in FIG. 26 , the display device 200 may display an AR carpet 2510′ on the changed lane and may map and display AR digital signage 2521, 2522, 2523, and 2524 corresponding to a plurality of pieces of POI information included in the building that can be entered.

In this case, in FIG. 26 , the AR digital signage 2521, 2522, 2523, and 2524 may be displayed in a form as if the signage is laid on the AR carpet 2510′, but the present disclosure is not limited to such a display form. For example, the plurality of pieces of AR digital signage 2521, 2522, 2523, and 2524 may be displayed on the AR carpet 2510′ as AR objects provided in a signboard form or a floating form.

Meanwhile, when the driver continues to drive straight without changing lanes to the right lane 2502 after the AR carpet 2510 is displayed, the AR carpet 2510 may disappear after a predetermined time.

Although the AR carpet in the form of guiding entry to the building area has been described above, in an embodiment, an AR carpet informs the driver not to enter a specific area (e.g., an area under construction or a restricted area). For example, an AR carpet may inform the driver to continue to maintain the current lane. In this case, when the current lane is maintained, AR digital signage related to a building that can be entered may be mapped and displayed on the AR carpet.

Also, according to some embodiments, an AR carpet having a form of an arrow branched to guide various entry routes or an AR carpet that guides one entry route may be mapped and displayed. In this case, AR digital signage corresponding to representative POI information may be mapped and displayed on each branched AR carpet.

FIG. 27 is a diagram illustrating that a display device according to an embodiment of the present disclosure communicates with a vehicle and a digital signage platform providing system.

FIG. 27 is a diagram illustrating that a display device 200 according to an embodiment of the present disclosure communicates with a vehicle 100 and a digital signage platform providing system 1000.

In FIG. 27 , the display device 200 according to the present disclosure may include a communication unit 2710, a display unit 2720, and a processor 2730. The digital signage platform providing system 1000 may include a platform providing apparatus 800 and one or more clouds 900 for communicating with the platform providing apparatus 800.

The display device 200 may receive the sensing data of the vehicle from a system such as a sensor, a vehicular electronic device, and an advanced driver assistance system (ADAS) provided in the vehicle 100 through the communication unit 2710.

Through the communication unit 2710, the display device 200 may transmit the sensing data of the vehicle to the digital signage platform providing system 1000 and may receive POI information associated with the sensing data of the vehicle. To this end, the digital signage platform providing apparatus 800 and the cloud 900 may be communicatively connected to each other.

The display unit 2720 of the display device 200 displays a driving image acquired through a vision sensor (e.g., a camera, an image laser sensor, etc.) of the vehicle. The processor 2730 of the display device 200 transmits information related to the driving image to the digital signage platform providing system 1000 through the communication unit 2710.

The digital signage platform providing system 1000 may perform information filtering and processing to perform merging for generating the AR digital signage on a floor-by-floor basis on the basis of the sensing data of the vehicle received from the vehicle 100, map information associated with the sensing data of the vehicle collected from the cloud 900, POI information, the spatial location of the building including a plurality of pieces of POI information, floor number information, POI-related advertisement information, and information on the driving image received from the display device 200, and the like and may transmit the merging result to the display device 200.

The display device 200 may receive a result of a rendering request that is received from the digital signage platform providing system 1000 to generate the AR digital signage on a floor-by-floor basis and may map the AR digital signage to the building in the driving image on a floor-by-floor basis through the processor 2730. Also, the display device 200 may receive a result of a rendering request that is received from the digital signage platform providing system 1000 to generate an AR carpet for guiding entry to a specific area and may map the result on the road in the driving image through the processor 2730 in the form of an AR carpet. To this end, the processor 2730 may be embedded in or interoperable with an AR engine.

The display device 200 may vary the display area to which the floorwise AR digital signage is to be mapped on the basis of the shape of the image of the building in the driving image acquired through the vision sensor and the sensing data of the vehicle 100 (the current location, the driving speed, and the driving direction of the vehicle) received from the vehicle 100. For example, the display device 200 may vary the display area from the lateral side of the building area in the driving image to the front side and map the AR digital signage on a floor-by-floor basis on the basis of the driving speed of the vehicle and the distance between the current location of the vehicle and the current location of the building.

The display device 200 may move and map, to the AR carpet, AR digital signage that has been mapped on the building on a floor-by-floor basis on the basis of the sensing data of the vehicle 100 (the current location, the driving speed, and the driving direction of the vehicle) received from the vehicle 100.

The display device 200 may transmit information on the varied display area to the digital signage platform providing system 1000 and may receive the sensing data of the vehicle from the vehicle 100 in real time and vary the display area in real time. Here, the varied display area may be determined to be a location other than the building area in the driving image so as to secure visibility, and the other location may be, for example, a road edge adjacent to the building area, a guard rail, or a sidewalk adjacent to the building area, and the surface of a driving road. Also, the varied display area may be the AR carpet mapped on the road in the driving image.

As described above, according to some embodiments of the present disclosure, when conditions for a vehicle to enter a building area are satisfied, it is possible to significantly improve visibility by displaying AR digital signage on an AR carpet on a road differently from the conventional method of mapping and displaying AR digital signage on a building on a floor-by-floor basis. Also, by mapping and displaying a plurality of pieces of AR digital signage and an AR carpet on a road in a driving image rather than on a building in order to secure the visibility of advertisement signage while the vehicle is about to or is expected to enter the building, it is possible to help safe driving because visual information is provided on a road ahead without the need for the driver to change his or her gaze to the building. Also, when the appearance of an obstacle is detected in the driving direction of the vehicle, the driver may reliably recognize the obstacle and drive safely by stopping the display of the AR carpet and moving and mapping the image of the floorwise AR digital signage to another display area in the driving video or increasing the transparency of the AR digital signage and mapping the AR digital signage.

The present disclosure can be implemented as computer-readable codes (applications or software) in a program-recorded medium. The method of controlling the autonomous vehicle can be realized by a code stored in a memory or the like.

The computer-readable medium may include all types of recording devices each storing data readable by a computer system. Examples of such computer-readable media may include hard disk drive (HDD), solid state disk (SSD), silicon disk drive (SDD), ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage element and the like. Also, the computer-readable medium may also be implemented as a format of carrier wave (e.g., transmission via an Internet). The computer may include the processor or the controller. Therefore, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, unless otherwise specified, but rather should be construed broadly within its scope as defined in the appended claims, Therefore, all changes and modifications that fall within the metes and bounds of the claims, or equivalents of such metes and bounds are therefore intended to be embraced by the appended claims.
